Factorise : ` 25 x^2 - 30xy + 9 y^2`

Factorise 25x^(2) - 30xy + 9y^(2) . The following steps are involved in solving the above problem . Arrange them in sequential order . (A) (5x - 3y)^(2) " " [ because a^(2) - 2b + b^(2) = (a-b)^(2)] (B) (5x)^(2) - 30xy + (3y)^(2) = (5x)^(2) - 2(5x)(3y) + (3y)^(2) (C) (5x - 3y) (5x - 3y)

Factorise : 9x^(2) - 30xy + 25y^(2)

Factorise : x^2+y-xy-x

Factorise: 25/4 x^2-y^2/9

Factorise: x ^(2) - xy + y -x

Factorise : (v) x^(2) - 2xy + y^(2) - z^(2)

Factorise : 3x^2 + 6x^2y + 9xy^2 .

Factorise : (x^2 – 2xy + y^2) – z^2

(a) Factorise : 9x^(2) - 24 xy + 16y^(2) (b) Factorise : 25x^(2) + (1)/(25x^(2)) + 2
